Correlation p_B−p_Ṁ for a dipolar (solid black line), a quadrupolar (dashed black line), and an octupolar (dotted black line) topology in the unsaturated regime. Dashed blue lines: magnetic field prescriptions from See et al. (2017, S17) and Vidotto et al. (2014, V14). Blue crosses: magnetic field and mass loss prescriptions from Johnstone et al. (2015a, J15), Tu et al. (2015, T15), and Sadeghi Ardestani et al. (2017, SA17). In dark gray: excluded region in the dipolar case. Dashed dark red lines: prescriptions compatible with the Skumanich law for any magnetic topology. In light red: exponents corresponding to mass losses outside the envelope of Wood et al. (2005) data. The light gray band corresponds to the upper and lower bounds from Zeeman-Doppler imaging (ZDI) statistical studies (see Sect. 3.4 for more details).
